What's the math here? Austria gets 2-3 times as many tourists per capita, but consumes 20% less. Tourists spent 56 million nights in Czechia in 2023, while the 10 million residents presumably spend a bit less than 365 nights in the country: how big of an impact could there be?

I can see how the argument would apply to certain cities or resort regions, i.e. I bet Palma de Mallorca has a much higher daily consumption during the summer season than in the winter.
